Osamu Akimoto (Japanese: 秋本 治 Hepburn: Akimoto Osamu) is a Japanese manga artist born on December 11, 1952 in Katsushika, Tokyo. He is best known for his long-running comedy series Kochira Katsushika-ku Kameari Kōen-mae Hashutsujo, which was continuously published in Weekly Shonen Jump for 40 years from 1976 to 2016. With 1,960 chapters collected into 200 tankōbon volumes, it was the manga series with the highest number of volumes until it was overtaken by Dokaben shortly afterwards, being awarded a Guinness World Record for "Most volumes published for a single manga series." By February 2012, the series had sold over 155 million copies, making it one of the best-selling manga series in history. Akimoto debuted with Kochikame under the pen name of "Tatsuhiko Yamadome" (山止 たつひこ) in 1976. He changed to using his real name in 1978, after the series reached its 100th chapter.
In November 2010, Akimoto was one of several manga artists that held a press conference in opposition to Tokyo Metropolitan Ordinance Regarding the Healthy Development of Youths's Bill 156.
In February 2014, he drew the one-shot "Vocalo" which is set 50 years after the rise of Vocaloid technology and ran in the shōjo manga magazine Margaret. The following year, Grand Jump published his "Arii yo Jū wo Ute!" one-shot in January 2015.
